How It Works
The doodle canvas is built on HTML5 Canvas API. All drawing operations happen locally in the browser, no data is uploaded to the server. Supports pen, eraser, color picker, and opacity control. Uses Catmull-Rom interpolation algorithm for smooth strokes, simulating a realistic hand-drawing experience.
